OK guys, which is correct? Both are advertised to fit a 1959 DeSoto but the arm lengths are significantly different. I just don't see how they can both work in the same application.

I could do that but I have a spare that was included with the purchase of my car. It has the short arm and since I saw two different ones advertised that were said to fit my car, I just wondered which I needed if and when I needed one. I'm not hankerin' to take mine out until I have to.

Hi Fred,

I don't know if you ever got an answer to this. Assuming your 1959 is running the stock 361 2BBL low-deck B Block, I think you want the fuel pump with the short arm. I have a copy of Willem Weertman's book on Chrysler engines. In it he shows a layout of the first 1958 B-Block. It drove the fuel pump via an interesting mechanism that had a pushrod in a housing bolted over the front of the camshaft. One end of the pushrod rode on the cam, the other end pushed on the short fuel pump arm. I have a shop manual for a 1963 Chrysler. It still shows a short arm pump. I know that my 1952, which uses the earlier Hemi design, has a long arm which rides directly on the camshaft similar in shape to the first photo.

Fred -
Open the parts book. In the fuel section, there will be a listing of the correct fuel pump, by Chrysler number and Carter number. Check your current pump. If you have a Carter, it should have the Carter number stamped on the edge next to the surface that mounts to the engine. You have to look closely, but it's there. If you have the correct original pump, have that one rebuilt or rebuild it yourself with at kit from Then & Now. If not, I would search for the correct pump, or try to cross-reference with an aftermarket. Don't trust listings on ebay. The modern pumps will likely put out too much pressure when you only need 5 - 7 lbs.
